This is a funnel for filling mason jars. It's for a pint & half pint jars with mouths around 2 1/4" wide.It is oblong shaped on top to make pouring into the funnel easier while maintaining a smaller storage footprint.I designed the item as a solid object with the small side down to make it easier to print on less than perfect beds.To print use 0 infill and top/bottom layers. Adjust the number and thickness of perimeters to make the part as thick as you want.
